Perfect Natto Spores

I've been making natto for a few weeks. I have made natto using spores from three different companies. When I use this natto starter it looks like it snowed on top of my natto and the neba neba strings are so thick that it's difficult to pull the natto beans apart. The difference between this product and others is significant and very visible. This is the freshest most easily activated spore I have found and it makes the tastiest natto! These spores are significantly better than any other I have used.

It worked!

I'd tried making natto three times before (with culture I bought elsewhere) and failed each time—it's a notoriously tricky ferment—but Cultures for Health's starter and instructions worked, and this morning I had fresh natto with miso rice and scallions. It was great!
